In van [or Zl yew E1 awaalzm Patented Nov. 8, 1932 PATENT FFHCE EUGENE BIANCALANA, 0F BROOKLYN, NEW YORK BOTTLE Application filed This invention appertains to new and useful improvements in electrical heaters, and more part"cularly to a novel heating attachment for bottles.

An important object of the invention is to provide the combination of a bottle and heater in the outlet thereof whereby the contents of the bottle will be heated as he same is poured through the outlet.

Another important object of the invention is to pro -ide a heat attachment especially adapted for nursing bottles, wherein the heating attachment will become automatically energized when the same is in tilted use.

These and other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings Figure 1 represents a side elevational view of the novel nursing bottle attachment.

2 represents an enlarged fragmentary longitudinal sectional view through the structure shown in Fig. 1.

Fig. 3 represents a cross sectional view taken substantially on line 33 of Fig. 2.

closing the electrical connection between the ctrical elements involved.

Referring to the drawings wherein like numerals designate like parts, it can be seen in 1, that numeral 5 represents a nursing 5 bottle having a threaded neck 6. Numeral 7 generally refers to the'attachment which includes the tubular shell 8 having the enlarged internally threaded end portion 9 defining an internal shoulder between which and the end of the neck 6 the packing 10 is located.

Numeral 11 represents a sheli which is internally spaced from the enlarged end portion 9, extending tron the shell 8 adjacent. the packing 10 as clearly shown in Fig. 2.

The outer end 01" this sleeve 11 is provided with an internal sleeve disposed flange 12 against which the packing 13 is disposed.

The other end of the shell 8 is e:-t"crnally threaded for engagement into the rim l l over which the nipple 15 can be stretched. This rim 1% is provided with an internal flange 16.

As is clearly shown in Fig. 5, the heater assembly is provided at each end with. a disklike member 17 between which extends a plurality of? fluid conducting tubes 18, the ends of the tubes extending through the headers 17-17 and having the heating coils 19 convolutec. around the same while being spaced therefrom by the spacers 20, the spacers 29 each b ing provided with a plurality of ribs 21 agot which the convolutions of the coils 19 engage.

its aoparent in 2, the innermost header 17 engages against the packing 13 while the outermost header 17 engages against the flange 16 of the rim 14.

The innermost header 17 is provided with a pair or packing glands 2222 through which the connecting rods 23-23 are slidahly disposed.

The innermostheader 17 has a sectional socket 24 mounted on the bottle side thereof and in this socket structure 24, the ball 25 is 9 operative, the latter being provided with an arn equipped with a float 27 at its free end.

As is clearly shown in Fig. 6, the arm 26 provided with a pair of diverging leg members 28-28 connected to the arcuate plate 29 which is equipped with contact rollers 3030 for iding engagement with the conductor ring 31 which is carried by the outer ends of the rods 2323.

The inner ends of the rods 2323, carry the contact r plate 32 on which the contacts 3282 are provided. On the outermost header 17 are the brackets (iii-33 equipped each with a contact 3%, with which a corresponding contact 32 is engageable.

9 shows that the coils 19 are in two groups, a pair of coils being in each group and the two groups being connected in parallei with the battery circuit 20 through the aforementioned switch means, so that in the event one set of coils burns out, the other will be available.

It can now be seen, by observing 2 that when a bottle is uilted from a vertica position to the horizontal position shown in F 2, the float will be actuated so that the rollers 30 will be removed from the conductor ring 31, thus permitting the spring 35 to urge the contactor 32 into engagement with the contacts 3%l8at. This results in the energi- Zation of the coil springs 19 and this will continue, until the bottom is again brought to a vertical position, or until the contents of the bottle has become exhausted, in which event the 527 lowers to a position exerting against the ring 31 so that the tension of the spring 35 is overcome to the end that the battery circuit connection shown in F 9 is broken.

Obviously, the darts oi the device above described are easily demountable tor the purpose of repair or replacement of elements without diiiiculty.

Figs. 10 to 13 inclusive disclose a modification of the invention, which is simply a bottle with the novel heater attached thereto, but eliminating the automatic current controlling factor.

In Fig. 10, numeral 5 represents the bot le, while character reference 6a generally refers to the attachment, which as shown in Fig. 11, includes a shell 8/; engaged with the neck 7a of the aforementioned bottle 5a. The heating means and construction of the heater assembly is identical with the construction or" the device as disclosed in Figs. 2 and 5, excepting that the numeral 35 represents an press air inlet tube extending from the point 36 on the outside of the shell to a point adjacent the bottom of a bottle and diverged in the manner disclosed by numeral 37.

As before explained, the attachment disclosed in Figs. 10 to 13 inclusive is without the switch means, there being a manual switch 38 in the battery circuit 89 for controlling the heating elements 19a of this particular form of the invention, the switch being extraneous to the attachment per se.

Obviously, as the contents of the bottle is poured out, air passes into the bottle through the tube 85, and as the air goes into the bottle through the tube, the same is heated as is the fluid passing outwardly through the attachment.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having, thus described my invention, what I claim as new is:

1. A nursing bottle comprising in combination, a nipple, and a heating unit interposed between the nipple and the bottle.

2. A nursing bottle comprising in combina tion, a nipple, a heating unit interposed between the nipple and the bottle, and a float controlled switch in the bottle for controllin the said heating unit.

3. In combination, a bottle, a heating unit at the outlet of the bottle, and an air inlet tube extending from a point adjacent the heating unit to a point in the bottle adjacent the bottom of the bottle, said tube extending in close proximity to thesaid heating unit.

4. A heating attachment for nursing bottles comprising a shell having one end adapted to engage the neck of a nursing bottle, the

other end of the shell being adapted to engage a nursing nipple, a partition in each end of the shell, and a tube extending longitudinally in the shell and opening at its ends thru the partition, and a heating element on the said tube and between the said partition.

in testimony whereof l my signature.

EUGENE BIANCALANA.
